The DOM method getElementById(id) returns null if the identified
element doesn't exist. Therefore you can code:
if (!document.getElementById('msgsubject')) return;
or:
if (!document.getElementById('msgsubject')) return
alert("Error: 'msgsubject' not found");
or:
if (!document.getElementById('msgsubject')) return
registerError("msgsubject", "not found");
etc.
